Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

Complement C5b-9 and Cancer: Mechanisms of Cell Damage, Cancer Counteractions, and Approaches for Intervention
In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

RAB31-Mediated Endosomal Trafficking Is Defective in RUNX1 Haplodeficiency
Conclusions: These studies provide the first evidence that RAB31 is a direct transcriptional target of RUNX1 and a mechanism for RAB31 downregulation in RUNX1 haplodeficient patients. Downregulation of RAB31 or RUNX1 results in impaired endosomal maturation/trafficking, and this may contribute to the defective handling of α-granule proteins recognized in patients with RUNX1 mutations.DisclosuresLambert: Sysmex: Consultancy; Rigel: Consultancy; Bayer: Membership on an entity's Board of Directors or advisory committees; Educational Concepts in Medicine: Consultancy; CSL: Consultancy; Novartis: Membership on an entity's...

LSC - 2017 - Re-education of tumor-associated macrophages by modulating histone deacetylases in lung cancer
Conclusions: Suppression of HDAC2 switches M2-like TAMs into M1-like phenotype and regulates tumor cell functions. Modulation of HDAC2 may provide a novel strategy for TAMs repolarization and cancer therapy.

Thick melanoma in Tuscany.
CONCLUSIONS: If we want to obtain better results on diagnosis of skin melanoma we have to think a new strategy. At least to think over the educational messages discriminating people more at risk of incidence of melanoma from people more at risk to die from melanoma, and to renewed active involvement of the Gen- eral Practitioners .

Fucoidan reduced the invasion of oral squamous cell carcinoma cells and modified their effects to macrophages
In this study, we analyzed the effects of fucoidan on invasion of OSCC cells, and their regulation to macrophages, trying to evaluate its role as a potential therapy for OSCC. CAL27 and THP-1-derived macrophages were used as models for OSCC cells and tumor-infiltrated macrophages in the in vitro study, respectively. The effects of fucoidan on invasion of OSCC cells and their recruitment to macrophages were analyzed by transwell assay. KIF4A siRNA transfection was performed to investigate its role in fucoidan-modulated OSCC cells invasion. CCL3-neutralizing antibody was added into the conditioned medium of OSCC cells to eva...

Role of Sirt3 in mitochondrial biogenesis and developmental competence of human in vitro matured oocytes
STUDY QUESTION Does Sirt3 dysfunction result in poor developmental outcomes for human oocytes after in vitro maturation (IVM)? SUMMARY ANSWER Inefficient Sirt3 expression induced decreased mitochondrial DNA copy number and biogenesis, and therefore impaired the developmental competence of human IVM oocytes. WHAT IS KNOWN ALREADY Cytoplasmic immaturity in IVM oocytes may lead to reduced developmental competence. Mitochondrial dysfunction results in the accumulation of free radicals and leads to DNA mutations, protein damage, telomere shortening and apoptosis. SIRT3 (in the Sirtuin protein family) has emerged as a mitochon...

Insulin response dysregulation explains abnormal fat storage and increased risk of diabetes mellitus type 2 in Cohen Syndrome
This study, in association with the in-depth analysis of the metabolic status of the patients, thus allowed us to recommend appropriate nutritional education to prevent the occurrence of diabetes mellitus and to put forward recommendations for the follow-up of CS patients, in particular with regard to the development of metabolic syndrome. We also suggest replacing the term obesity by abnormal fat distribution in CS, which should reduce the number of inappropriate diagnoses in patients who are referred only on the basis of intellectual deficiency associated with obesity.
